A road controller system includes A road controller system comprising: a data store to store an active traffic policy; a processor subsystem to: determine a speed or platoon size of a vehicle platoon traveling on an area controlled by the road controller system; and determine a change to the speed or platoon size of the vehicle platoon, the change based on the active traffic policy; and a transceiver to transmit a control message to the vehicle platoon to implement the change to the speed or platoon size of the vehicle platoon. ## Claims ### Claim 1 A road controller system including a plurality of road controllers, comprising: a data store to store an active traffic policy, the active traffic policy including rules to control traffic in a controlled area to reduce noise pollution of vehicle platoons; a sensor array interface to receive sensor data, the sensor data including road condition data; a processor subsystem to: access a status message received from a vehicle platoon traveling on an area controlled by a road controller of the plurality of road controllers in the road controller system, the status message including a platoon identifier and a number of vehicles in the vehicle platoon, and the status message transmitted to the road controller when the vehicle platoon enters the area controlled by the road controller; determine a platoon size of the vehicle platoon based on the status message received from the vehicle platoon; determine a change to the platoon size of the vehicle platoon, the change to the platoon size based on the active traffic policy and the road condition data; and cause transmission of a control message to the vehicle platoon to implement the change to the platoon size of the vehicle platoon. ### Claim 2 (depends on 1) The system of claim 1, wherein the active traffic policy is updated from a road controller broker. ### Claim 3 (depends on 2) The system of claim 2, wherein the processor subsystem is to: determine that the road controller broker is unavailable; and activate a default policy as the active traffic policy when the road controller broker is unavailable. ### Claim 4 (depends on 1) The system of claim 1, wherein the active traffic policy is managed by the road controller system. ### Claim 5 (depends on 1) The system of claim 1, wherein the active traffic policy is accessed from a road controller broker, the road controller broker controlling the plurality of road controllers in the road controller system. ### Claim 6 (depends on 1) The system of claim 1, wherein the rules to control traffic in the controlled area include rules to control traffic in a residential area to reduce noise pollution of vehicle platoons operating in the residential area. ### Claim 7 (depends on 1) The system of claim 1, wherein the sensor data further includes weather data, and wherein the determined change to the platoon size is further based on the weather data. ### Claim 8 A method of operating a platoon with a road controller system, performed by a road controller of a plurality of road controllers in the road controller system, the method comprising: accessing an active traffic policy, the active traffic policy including rules to control traffic in a controlled area to reduce noise pollution of vehicle platoons; receiving sensor data from a sensor array interface of the road controller system, the sensor data including road condition data; receiving a status message received from a vehicle platoon traveling on an area controlled by the road controller, the status message including a platoon identifier and a number of vehicles in the vehicle platoon, and the status message transmitted to the road controller when the vehicle platoon enters the area controlled by the road controller; determining a platoon size of the vehicle platoon based on the status message received from the vehicle platoon; determining a change to the platoon size of the vehicle platoon, the change to the platoon size based on the active traffic policy and the road condition data; and transmitting a control message to the vehicle platoon to implement the change to the platoon size of the vehicle platoon. ### Claim 9 (depends on 8) The method of claim 8, wherein the active traffic policy is updated from a road controller broker. ### Claim 10 (depends on 9) The method of claim 9, further comprising: determining that the road controller broker is unavailable; and activating a default policy when the road controller broker is unavailable. ### Claim 11 (depends on 8) The method of claim 8, wherein the active traffic policy is managed by the road controller system. ### Claim 12 (depends on 8) The method of claim 8, further comprising: accessing the active traffic policy from a road controller broker, the road controller broker controlling the plurality of road controllers in the road controller system. ### Claim 13 (depends on 8) The method of claim 8, wherein the rules to control traffic in the controlled area include rules to control traffic in a residential area to reduce noise pollution of vehicle platoons operating in the residential area. ### Claim 14 (depends on 8) The method of claim 8, wherein the sensor data includes weather data, and wherein determining the change to the platoon size of the vehicle platoon comprises using the weather data to determine the change. ### Claim 15 (depends on 8) The method of claim 8, wherein the sensor data includes road condition data, and wherein determining the change to the platoon size of the vehicle platoon comprises using the road condition data to determine the change. ### Claim 16 At least one non-transitory machine-readable medium, including instructions for operating a platoon with a road controller system, which when executed on a machine for a road controller of a plurality of road controllers in the road controller system, cause the machine to perform the operations comprising: accessing an active traffic policy, the active traffic policy including rules to control traffic in a controlled area to reduce noise pollution of vehicle platoons; receiving sensor data from a sensor array interface of the road controller system, the sensor data including road condition data; receiving a status message received from a vehicle platoon traveling on an area controlled by the road controller, the status message including a platoon identifier and a number of vehicles in the vehicle platoon, and the status message transmitted to the road controller when the vehicle platoon enters the area controlled by the road controller; determining a platoon size of the vehicle platoon based on the status message received from the vehicle platoon; and determining a change to the platoon size of the vehicle platoon, the change to the platoon size based on the active traffic policy and the road condition data; and transmitting a control message to the vehicle platoon to implement the change to the platoon size of the vehicle platoon. ### Claim 17 (depends on 16) The machine-readable medium of claim 16, wherein the active traffic policy is updated from a road controller broker. ### Claim 18 (depends on 17) The machine-readable medium of claim 17, further comprising: determining that the road controller broker is unavailable; and activating a default policy when the road controller broker is unavailable. ### Claim 19 (depends on 16) The machine-readable medium of claim 16, wherein the active traffic policy is managed by the road controller system. ### Claim 20 (depends on 16) The machine-readable medium of claim 16, further comprising: accessing the active traffic policy from a road controller broker, the road controller broker controlling the plurality of road controllers in the road controller system. ### Claim 21 (depends on 16) The machine-readable medium of claim 16, wherein the rules to control traffic in the controlled area include rules to control traffic in a residential area to reduce noise pollution of vehicle platoons operating in the residential area. ### Claim 22 (depends on 16) The machine-readable medium of claim 16, further comprising receiving sensor data from a sensor array interface incorporated in the road controller system.
